A reliable modeling of \(\gamma \)  process flows involves typically an extended network of about two thousand nuclei and
ten thousand reactions for nuclei with masses up to around 210 [1]}.
The nucleosynthesis develops in the neutron-deficient region of the chart of nuclides [2]}, [3]}, [4]}, whose masses and decay rates are mostly well known experimentally.
The reaction rates of such critical reactions, in particular for the photodissociations,
then represent the main uncertainty from the nuclear physics point view in predicting the elemental abundances produced in \(\gamma \)  process [5]}, [6]}.
